Quarrying // 25
On average, the quarrying specialists at Recycling Lahnau are
in action at around 20 different locations. One of the largest
construction sites at the moment is the quarrying of limestone
for Rheinkalk GmbH in Dornap near Wuppertal. Between the
spoil and the actual limestone, there is a so-called cleaning cut
containing some relatively good limestone, which has to be sieved
before it can be prepared in order to clean out the impurities.
The resulting stone material is then used to produce mineral
mixtures. In Dornap, the company provides all machines and
staff. Twelve earth-moving machines, including four excavators
and three wheel loaders from Liebherr, are in operation here. In
addition, there is also a mobile hammer crusher, a mobile impact
mill with integrated sieve unit, and a coarse sieving machine.
In total, there are 75 large, modern machines. These include
crawler excavators with an operating weight of 28 to 99 tons,
rigid-frame dumper trucks with between 44- and 72-ton payloads,
articulated trucks in the 33-, 39-, 44- and 55-ton classes, crawlers
for various operations, in-hole and outer-hammer drilling rigs for
various borehole diameters, wheel loaders of all sizes, mobile
crushers, sieve systems and hydraulic hammers. Forty-eight
machines bear the Liebherr name, including all 15 wheel loaders,
15 crawler excavators, all eight crawlers and nine articulated
trucks. “The quality and resilience of the Liebherr machines are
right, and that is especially important for us,” says Ralph Lang.
“We also only hear positive feedback from the drivers: good hand-
ling, good performance, plenty of space and comfort in the cab.
We even have excavator drivers who state categorically that they
don’t want any other brand.”
The four reverse gears on the articulated trucks are praised
especially highly. They make it easy to cover short distances in
reverse, alleviating the need for maneuvering and saving lots of
time. The handling of the retarder is something else the drivers rate
highly. A lever on the dashboard freely adjusts the effectiveness
between 0 and 100 %, adjusting it perfectly to the profile of the
terrain. That relieves the service brake and creates greater safety.
Another decisive criterion for the use of so many Liebherr
machines is flexibility. “As a service provider, we have to be able
to respond extremely flexibly to customer wishes, and to make
enough of the right machines available for a certain period of
time,” explains Ralph Lang. “Where the next job is and exactly
what is to be done there is always decided a new, sometimes on
very short notice. Liebherr and, in particular, the rental service of
Liebherr Mietpartner GmbH give us exactly the flexibility we need.
We have been collaborating successfully since 2003. We have
competent consultants and use their experience when it comes
to, say, the right choice of attachments. The machines are ordered
and built exactly to our wishes and expectations. And even if a
job is arranged on very short notice, we are able to bridge the
time up to the delivery of a new machine with rental machines
that are available immediately.”
With 48 machines in operation nationwide, service is a key factor.
In most cases, a mechanic can be on site the same say or, at the
latest, the following day. “The availability and response time of
the Liebherr service teams are superb. The collaboration with
Liebherr is perfect for our needs,” Ralph Lang tells us.
“We even have excavator drivers who
state categorically that they don’t want
any other brand.”
